Having successfully concluded their first case, teenaged ghost hunting duo Carolyn Hunter and Frankie Allen are back in the mundane world with a bump as the new school term starts. They are just starting to settle into the daily routine, when they are approached by twins Ruby and Lewis Morgan. Recovering from a recent bereavement, the twins are experiencing creepy paranormal activity in their family home, and are desperately in need of help. Carolyn and Frankie agree to investigate, and, as the phenomena become increasingly menacing, find themselves stretched to their limits. Nothing is as it appears, and the ghost hunters may have grievously underestimated their opponent!
